How about 10,5-11 % for 5W-30/10W-30 and 10 % for 0W-40 ?

Gentlemen ,would you please let me make a silly question?
Is it realy necessary for hydroprocessed to stand for hydrocracked??
It could mean hydro synthesis , H synthesis ,H+C synthesis.??

Hydroprocessed and hydrockracked oils are Group III oils received by different methods of hydrogen treatment. May be we have to use only a general name "Group III" when we don't know exactly what was the type of process. If I am not mistaken, there are:
- Hydrogen processing. It may be made to different depth: from hydrotreatment to hydrocracking
- Hydroisomerisation
- Hydrodewaxing (catalytic). It's made after hydrocracking or solvent dewaxing
- Hydrocracking (catalytic)
Most know brand names of Group III oils:
Shell: Shell XHVI, VI > 140
British Petroleum: HC (Hyrdrockracker Component), VI > 125
Exxon: ExSyn, VI > 140
Chevron: Isosyn, VI > ?
Fuchs: MC (Molecularly Converted) , VI > ?

Buster,
Vous etes agent-provocateur
But knowing VI and type of base stocks it's possible to make a rough estimation of how many VM (Viscosity Modifiers) were used in one oil with reference to another. The comparison will be more accurate if you take oils of the same grade and weight spread, i.e. compare 5W-40 with 5W-40 or 10W-30 with 10W-30 etc.
Primus, based on Mobil's PDS, they do use the term synthetic base stocks, including PAO's. Now this does sound speculative to some degree. I always took it as esters, being the other base stocks, which I still believe is the case. Looking at VI tells me nothing.

At some point, I am going to send off a sample to Terry to have the new Mobil 1 R looked at far more in depth. Maybe this will let us know for sure.

Forget about base stocks, enjoy pictures of oil packaging for Japaneese market !

Hydroprocessing is a general term meaning that hydrogen is percolated (or hydrogen sulfide is added) through the hot base oil to improve it stability.
All decene-1 PAO's are sent to another step after polymerization called "hydroprocessing" which improves thermal stability on the high and low ends of the temperature scale.

Thus you can bring a confusion. The question was about ways of getting Group III oils. When manufacturers indicate oil base stocks as PAO + Hydprocessed (Mobil) or PAO + HC (Castrol), they mean PAO + Group III, but not PAO + hydroprocessed PAO.

What question? All I saw was a link to a Japaneese Mobil site?
Why then do we speak about hydroprocessing ? I thought we were replying to Yannis question about on hydroprocess vs. hydrocracking.
Primus, does this link that you posted answer your question on whether or not Mobil 1 is PAO? The above quote is off the US FAQ webpage.
This is from a Ferrari webpage:

As far as the dino/syn content of Mobil 1, I received this email from Mobil:
"All Mobil1 motor oils that have ever been introduced are fully synthetic motor oils and are not hydrocracked. Mobil1 motor oils only contain Group IV and V basestocks."
--------------------------------------------------------------------------------
This seems pretty clear to me. No Group III. What am I missing?
